Answer:
gametes
Explanation:
In the human reproductive process, two kinds of sex cells, or gametes (GAH-meetz), are involved. The male gamete, or sperm, and the female gamete, the egg or ovum, meet in the female's reproductive system. When sperm fertilizes (meets) an egg, this fertilized egg is called a zygote (ZYE-goat).
Tissues are below complex organs.
<h3>What are the tissues?</h3>
- The body is made up of four different types of tissue: epithelial, connective, muscular, and nervous. Each has a purpose for which it was created.
- Connective tissue, epithelial tissue, muscular tissue, and nerve tissue are the four fundamental forms of tissue. Other tissues are held together and supported by connective tissue (bone, blood, and lymph tissues). A coating is provided by epithelial tissue (skin, the linings of the various passages inside the body).
- Tissue that gives bones their strength and structure. Compact tissue (the tough outer layer) and cancellous tissue make up bone (the spongy, inner layer that contains red marrow). Osteoblasts, which build new bone, and osteoclasts, which break down existing bone, maintain bone tissue.
- Blood tissues can be found inside blood vessels, including arteries, arterioles, capillaries, venules, and veins (for more information on the names of individual blood vessels and the course the blood takes, see systemic circulation), as well as inside the heart's chambers.
To find the level is just below organs in complexity:
